轻型客车车架动态应力应变特性分析

Analysis and Research for Dynamic Stress and Strain of Chassis of Light Duty Passenger Car

在建立的车架数学和力学模型基础上,揭示了车架在典型路面激励下的动态响应及应力应变状态,为该车在山区路况下车身产生开裂、高速行驶中稳定性等问题的解决在车架特性上找到影响因素.

Based on establishment of mathematic and dynamic model of the chassis, the dynamic response and stress state and strain state in typical road stimulating is analysied in this paper. This analysis is verified by finite element method and chassis characteristic experiment. It can solve the body crack problem and improve the vehicle ride performance.
